I will be receiving my new SX in a couple days from San Diego and I know that removing the secondary muffler along with replacing the ECM with race tune are very beneficial but I'm curious at what point do I start making changes? Right away or after the initial break-in period? It will only have 9 miles on it when the shippers drop it off.

What are the most common changes to make to maximize these bikes; it will only be a street bike with no track days? I'm not looking to throw a ton of money at it, but things that make the comfort and some performance better. Any California emissions items i should look at removing?

Thanks
Jeremy
